More specifically, the present invention relates to an on-machine-seamable industrial fabric, such as an on-machine sewn press fabric used in the press section of a paper machine. Background of the Invention In the papermaking process, a fiber pack is produced by depositing a fiber slurry, that is, a water-based dispersion of fibrous material, deposited on a mobile machine in the forming section of a paper machine. Comes from fabric. A large amount of water will be collected through the forming fabric to drain out, leaving fibrous pupae on the surface of the forming fabric. 15 20 The fibers that have just been formed from this forming section are fed to a crimping section that contains a series of roller sets. The fibrous pupae will be pressed by the fabric and passed through the roller set, or under normal circumstances, it will be passed between the two urines. In the scales, the fibrous embryos will suffer; = and the water is squeezed out, and the fibrous embryos in the embryos will be transformed into -paper. Its water inside the paper. 4 "'a thing is absorbed' and ideally, it will not return to it which contains at least one set of spins. The freshly made paper will be moved back to the handle, and the paper will eventually advance to a In the drying section, the rotating drying drum will be introduced with steam to dry the fabric inside-continuous rewinding of each of these 5 200402495 and other fabrics will press the paper against the surface of the drum. And the heating The drum will reduce the water content of the paper to the required level through evaporation. It should be understood that these forming, pressing, and drying fabrics will form endless loops on the paper machine and operate as a conveyor belt Please also understand that the production of the 5 paper is a continuous process and will be carried out with considerable catch. That is, the fiber slurry will be continuously deposited in the forming fabric in the forming section, while a new The finished paper will be continuously rolled into a roll after leaving the drying section. 'Although there was a time in the past, especially the pressing fabric, it was only supplied in 10 unexplained forms. This is because the newly formed The fibrous pupae are easily pressed by the rollers in the roller. The unevenness in the object creates a mark. A fabric that has no seams and seams, such as the fabric made by the conventional endless weaving method, can be used in its longitudinal direction (in the machine direction) and transverse direction (cross the machine) (Direction) all have the correct ,,, and ° structure. A seam, for example, when the pressed fabric is installed on a papermaking machine 15, is used to seal the joint into an endless form of seam, which represents L The uniform structure of the old and new objects will be interrupted. Therefore, the use of a seam will greatly reduce the possibility that the fiber embryo will be marked in the rolling wheel. For this reason, any available machine The seams of the top-stitched crimp fabric must be able to operate under load like the rest of the crimp fabric, that is, it must be compressed under the pressure of Komatsu ^ Net Temple, and must have the same permeability and Breathable pens and pens can prevent the produced paper products from being periodically marked by the seam area. Kg has the obvious technical obstacles that these needs show, and it still needs to be developed _ ^ 了Press-stitched fabric stitched on the machine, because the fabric can be easier and 200402495 The entire ground is installed on the crimping section. Finally, the obstacles are overcome by the improved crimping fabric, whose seams are made by forming sewing loops on the cross-cut edges at both ends of the fabric. The sewing loop itself is formed by the machine direction (MD) yarn of the fabric. The seam is closed by joining 5 ends of the pressed fabric together, that is, the sewing loop between the two ends of the fabric Overlap, and pass a needle or pin through the channel formed by the overlapping sewing loops, and thread the two ends of the fabric together. Needless to say, install a crimped fabric that can be sewn on the machine. Will be easier and less time-consuming than installing an endless crimped fabric on a paper machine. 10 A method system that can be used to make such a crimped fabric with the seam that can be joined on a paper machine The fabric is flat-weave. In this case, the warp yarn is the machine direction (MD) yarn of the pressed fabric. To form such sewing loops, the warp yarns at both ends of the fabric are reversed in a direction parallel to the warp yarns to weave a length back into the fabric body. Another better technique is the modified endless knitting method. The endless knitting method is normally used to make an endless loop of a fabric. In the modified endless weaving method, the weft or filling yarn is continuously woven through the loom back and forth, and a loop is formed around one edge of the fabric to form a pin in each stroke to form a loop. ring. In the end, the weft or filled 20 yarn system of the MD yarn in the pressed fabric is continuous, so the sewing loop made in this way will be more capable than weaving the end of the warp back to the ends of a plain weave. Producers are stronger. There is another technical system. A multiaxial pressure-bonding fabric for machine-sewing which is used as the pressure-bonding section of a paper machine is made of a base fabric layer, which rolls a fabric strip into a plurality of continuous threads. Circle, and the spirals will h h κ • C ·, heart ",. R. * U. · 7 200402495 against each other and fixed to the phase _. The endless base fabric layer thus made will be Flattened to form the first and second fabric layers' and joined to each other at the reversal of their birch edges. 4 Reversed at each lateral edge, the number of longitudinal frying will be divided by each of the fabric strips. Finely formed into a sewing loop. The first and second fabric layers can be overlapped with each other by needle punching the wool material. When the pressed fabric is installed on a paper machine, it can be guided by two pins. The through holes formed by the suture loops in the miscellaneous place are connected to form endless loops. 10 In each of the above cases, the 'spiral stitching coils can be fixed to the suture loops at both ends. The stitching loops on each end of the intersecting-spiral stitching loop _, and then passing the pin through the yarn and stitching Circle through the through hole, so that the spiral stitching coil 15 of the 2 :: r's ... 'the fabric is ㈣ ㈣ ::, the respective spirals to intersect each other, and then pass another -pin thread through " Find the holes formed by the suture coils in series to make the two ends D of the object form an endless loop. 20 The last step of making ~ t fabric-stitchable fabric is to pierce at least-the outer surface with a multi-layer staple fiber material. This acupuncture operation ^ = the fabric is joined together-the endless loop step is also entered at the same time. The read zone will also be covered by the acupuncture operation for accuracy. Bu, bi have the same penetration as the rest of the fabric and will be unloaded: Needle: After the process is over, the pins that join the fabric at both ends will be cut ~ The staple fiber material in the seam area will be cut To form a living film suitable for the region. 5Heibold fabrics are now open-ended 8 200402495 style, and will be boxed and shipped to customers who make paper. During this needling process, the pressed fabric is inevitably damaged. This is because the fibers used to drive the fibers of the staple fiber material into and pass through the pressing fabric will also hit and break or wear the yarn of the pressing fabric itself. Moreover, when the seam area of the pressed fabric is needled, at least some of the MD yarns forming the sewing loop, and (if any), the spiral sewing stitches will be damaged. Such damage inevitably weakens the entire seam and can even cause it to fail. In this connection, it should be understood that, in the case of a spiral stitch, only a small amount of damage can cause premature seam damage. Because a helical stitching loop extends laterally through the fabric in the seam area, a break at any point weakens a substantial portion of its length, causing it to tear or separate. In addition to pressing fabrics, there are many other types of industrial fabrics that are designed to be closed into endless form when they are intended to be installed on certain equipment. 15 For example, the dryer fabric of a paper machine can also be assembled into an endless loop when installed in the dryer section. The dry fabric can also be joined with a pin seam or a spiral seam, which are similar to the foregoing. In addition to dry fabrics, other industrial fabrics, such as corrugated belts, pulp forming fabrics, and pulp dewatering belts, are stitched in a similar manner. 20 In these fabrics, the MD yarn is also a stitch loop, and it is known to bend a yarn around a small radius, especially a single fiber yarn to form a loop, which will make the yarn in the loop area The wire weakens with increasing stress. Therefore, the entire seam will be weaker than the fabric body when in use. Since these seam loops are subject to load and repeatedly flex (and in some cases are compressed) during use

Furthermore, the spiral suture coil system can only use a limited number of structures. That is, they can only be made to a limited number of diameters and pitches (number of turns per unit length). Obviously, alternatives to this spiral stitching coil will be eagerly anticipated by the designers of industrial fabrics 5. The present invention can solve the disadvantages of these conventional technologies by providing a seam, which is less susceptible to damage that may cause premature failure of the seam. [Summary of the Invention] Summary of the Invention 10 The reason is that the present invention is an industrial fabric that can be stitched on the machine, and includes a base fabric that can be stitched on the machine, which has a machine direction MD yarn system, and a cross Machine direction CD yarn system. The MD yarns can be combined with the CD yarns in any suitable manner (such as interlacing, chemical, mechanical, etc.) to form a rectangular base fabric having a length, a width of 15 degrees, two longitudinal edges, Two lateral edges, a first side and a second side. The MD yarns will extend the length of the base fabric to form a sewing loop, etc. along its two lateral edges. If the industrial fabric is to be used as a press fabric for a paper machine, at least one layer of staple fiber material will be attached to one of the first and second sides of the base fabric. 20 The invention has two main embodiments. In the first embodiment, a number of loops are laid along the lateral edges of the base fabric. Each loop is between a pair of sewing loops and surrounds at least one CD yarn. The on-machine-seamable technical fabric is sewn into the form of an endless loop using such sewing loops and loops. According to this, the rings that surround at least one CD yarn and the suture pin 10 200402495 will provide an auxiliary reinforcement to the seam due to the reinforcements forming the suture loops. The loops also enable the enclosed CD yarn to strengthen the seam. In the second main embodiment, there are a number of stitching loops that will join the two lateral edges to each other. Each loop is placed between a pair of stitched 5 loops on one of its lateral edges and is joined by a first pin through which it passes. The loops will also be positioned between a pair of stitching loops on the other transverse edge and joined to the stitching loops by a second pin threading through them. The majority of the loops and the first and second pins will join the fabric into the form of an endless loop. Alternatively, a first set of sewing loops would be routed along one of its lateral edges, and a second set of 10 sewing loops would be routed along its other lateral edge. The loops of the first group are interposed between a pair of stitching loops at the lateral edge and are joined by a first pin threaded through. The loops of the second group are positioned between a pair of stitching loops on the other lateral edge and are joined by a second pin threaded through. The sewing ring of the first group will cross with the sewing ring of the second group, and then a third pin will be guided through the channel formed by the sewing rings of the 15 intersections, and the industrial fabric will be combined into one. Endless ferrule form. In this embodiment, the loop systems are used to replace one or more suture spiral coils. These loops give the seam a better resistance to flexing and are different from helical coils, with no components in the transverse or cross-machine direction. 20 The present invention will now be described in more detail with reference to the following drawings. Brief description of the drawings. Figure 1 is a schematic perspective view of an industrial fabric that can be stitched on the machine. Figure 2 is a cross-section of the industrial fabric that can be stitched on the machine along the line 2-2 of Figure 1. Figures 11 120042495 Figures 3A and 33 are cross-sectional views similar to Figure 2 and show the machine-sewnable industrial fabric of the present invention; and Figure 4AI44B is also similar to Figure 2 The cross-sectional view shows a modified embodiment of the on-machine-seamable 4-use fabric of the present invention. 5 [Embodiment] For a detailed description of the preferred embodiment, please refer to the drawings. Although it is not drawn in actual scale, it can show the present invention and its components. Fabric_ three-dimensional illustration. The fabric forms an endless loop when its ends 12, 14 are joined 10 at a seam 16. Fig. 2 is a cross-sectional view of the conventional industrial fabric 20 which can be sewn on the machine, taken along the line 2_2 of Fig. 1. The batting fabric 2 () includes a base fabric 22 that can be sewn on the machine, and the health care fabric 20 is a pressing fabric, and n layers of staple fiber material 24 will be needled into the base fabric 22. For clarity, the 15 staple fiber material 24 is only shown in the second figure—partially, but it should be understood that it will be pierced into all parts of the base fabric 22 during the needle = process, including The area of the seam 26. The short-fiber material 24 may include any segmented short fiber of a polymer resin used for manufacturing paper machine fabrics and other industrial processing fabrics, but is preferably selected from the group consisting of polyamide, polyester, polyolefin, and polyetherketone. And other resins. The industrial fabric 20 can also be coated on one or both sides, or impregnated partially or completely with a polymeric resin such as polyurethane or silicone, and coated by conventional methods in the field, such as Full width coating, dip coating and spray coating. Molten polymer particles can also be used to form a "cladding surface". Sintered metal particles can also be used to coat one or both sides of the fabric. 12 200402495 The on-machine-seamable base fabric 22 is made of machine direction (MD) yarn 28 in the longitudinal direction, and cross machine direction (CD) yarn 30 in the transverse direction. The MD yarn 28 will form a sewing loop 32, which will cross each other in series and pass a pin 34 through the channels formed by the crossing sewing loops 32 to form the seam 26. It should be seen that the base fabric 22 in Fig. 2 is made of plain weave, and the seam loops 32 are formed by turning the warp yarn ends at the lateral edges of the fabric 22 back into the body. As shown in Fig. 2, the MD yarns 28 are warp yarns of the base fabric 22. However, it should be understood that the base fabric 22 can also be woven using a modified endless weaving technique, in which weft yarns are continuously woven back and forth across the loom and woven around a loop-forming pin to form a sewing loop. And finally become the MD yarn of the fabric. Also, the base fabric 22 is shown to be woven with a double weave, but it should be understood that this is only an example, and the base fabric 22 may be woven with other weaves, such as: single, double, triple Or weaves or the like may be superimposed to include a plurality of fabric layers. In the latter case, the base fabric is laminated to include a plurality of fabric layers, and one or more or all of these fabric layers can be stitched on-machine and are made in accordance with the present invention. As mentioned above, the industrial fabric 20 is a press fabric. Therefore, the base fabric 22 may be needle-punched on one or both sides of the base fabric 22, or one or more layers of the short ciliated pad material 24, Some way to overlay. Alternatively, the industrial fabric 20 may be used in another section of a paper machine, i.e., in a forming section or a drying section, or as a base fabric for a paper-processing industrial belt (PIPB) coated with a polymer resin. 200402495 Each of these MD yarns 28 and CD yarns 30 can also be any kind of yarn generally used for weaving paper machine fabrics or other industrially treated fabrics. That is, for example, single-fiber yarns of single-filament filaments, or plied / twisted yarns, that is, single-filament yarns or blended multi-fiber yarns, can be used as such yarns. Also, each of the 5 MD yarn 28 and the CD yarn 30 may be a covered yarn as shown in commonly assigned US Patent Nos. 5204150 and 5391419, the contents of which are hereby incorporated by reference. In addition, the filaments made of the MD yarn 28 and the CD yarn 30 are made of artificial polymer resin materials, such as polydonamine, polyester, polyetherketone, polypropylene, 10 polyolefin, and aromatic polyamide. , Polyurethane, polyketone, and polyethylene terephthalate (PET) resin, etc., or metal wires, which can be incorporated according to techniques well known in the industrial textile industry, especially the papermaking cloth industry. In the yarn. The pin 34 may be a single-stranded monofilament, a multi-stranded monofilament; a multi-stranded monofilament that is not twisted with each other, or plied, twisted, braided, or knitted; or 15 any other kind for closing Pins for the seams of cloth for paper machines. The pin wire 34 may also be a metal wire, or may be made of an extruded polymer resin material, such as those listed in the preceding paragraph. According to the present invention, the on-machine-seamable industrial fabrics described above can be made less damaging to premature seam failure. Please refer to FIG. 3A, which is a cross-sectional view of an on-machine-seamable industrial fabric 40 similar to FIG. 2 of the present invention. The base fabric 42 includes a seam 44 which contains a large number of sewing loops 46. The MD fabric 48 of the base fabric 42 is formed. The base fabric 42 also contains CD yarns 50 and the like, and if the industrial fabric 40 is a compression fabric, one or more layers of staple fiber material 52 will be needled therein. 14 200402495 As shown in section 3A®, there are some MD yarns 48 that do not form a sewing loop 46, but instead will tightly weave around the CD yarn zero to form a gap between the sewing loops 46, so that Iso-suture loops can be overlapped by the crossover rate. In at least some of these gaps, there are loops 54 and the like which will surround one or more 5 CD yarns 5G 'to form an additional additional sewing loop. When the on-machine-seamable industrial fabrics 40 are to be joined into the form of endless loops, the sewing loops 46 and the loops 54 and the like at the ends of the fabric will cross each other to create a through hole to accommodate A pin 56 passes through to join the two ends together. Please refer to FIG. 3B for a cross-sectional view of another example of an on-machine-seamable industrial fabric of the present invention. The base fabric 42 also includes the above-mentioned] y [D yarn 48 and CD yarn 50, etc.]. If the industrial fabric 40 is a pressing fabric, one or more layers of staple fiber material 52 will be needled therein. In Figure 3B, no ME ^, 48 will form a sewing loop. Instead, all MD yarns 48 are tightly wound around the yarns 50). In the gap between at least some 15 adjacent MD yarns 48, there will be a loop 54 surrounding one or more CD yarns 50, shaped like a sewing loop. When the fabric 40 is to be joined into the form of an endless loop, the loops 54 at both ends of the fabric 40 will be intersected with each other to create a through hole 'to allow the pins 56 to pass through and join the two ends together.

Among them, Figs. 4A and 4B are similar to Fig. 2 and are sectional views of industrial fabrics 60 and 80 which can be sewn on the machine, respectively. As mentioned above, the fabrics 60 and 80 each include a base fabric 62 that can be sewn on the machine, which includes a seam 64 containing a plurality of stitching loops 66 made of the MD yarn 68 of the far base fabric 62. The base fabric 62 also includes CD 15 200402495 = 70, etc., and if the industrial fabrics 60, δ0 are woven fabrics or glass ribbons, one or more layers of staple fiber material 72 will be needled therein. As shown in Figures 4A and 4B, the sewing loops 66 such as Yanxuan are not directly joined to each other. Instead, in the 4th wealth, each ring M will be used to connect the first ring and the second ring 76, 78 to each other. In the first side, the first loop 82, etc. will be connected to the stitch loop 66 at the ⑽-end of the fabric with a first pin 76, and the second loop 84, etc. will be connected to the stitch at the other end with a second lock thread. Ring 66 and so on. Each of the first ring 8㈣ is connected to the second ring 84 or the like in a third pin shape. 10 Referring to the embodiment shown in FIGS. 3A and 3B, the loops 54 can use 00 yarn 50 to strengthen the seam 44. ❿Figures 4A and 4B show a variation of the spiral seam of the conventional technology, in which the ring 74 does not extend in the direction of the CM, and if the part is damaged, the entire seam will be weakened. . -In general, the rings 54, 74, 82, _ can be one of several shapes M, such as circular, oval (rounded), skewed, long rounded, quadrilateral, or D-shaped. The cross-section of the material constituting these rings can be circular, stamped, or round), square, rectangular, or other cross-sectional shapes, and the diameter can be in the range of 0.15 to 1.0 mm. 20 These rings 54, 74, 82, and 84 can be made of metal or any of the aforementioned polymer resin materials, as if they were yarns used in the health textile industry, and can be flexible. Not lowering, or open mechanically at the other end by means of, for example, a clip. The ring can also use a prefabricated palm on one or all sides of the ring, and its deer spreads across the surface of the ring to provide a relatively constant pressure difference. 哕 rolled in & & 1 "sleeve盍 is permeable or impermeable

The loops 54, 74, 82, and 84 may be monofilaments, plied / twisted filaments, or knitted filaments. It can also be coated with additional polymeric resin materials. The loops as a whole can have a length of 0.70 to 3.0 mm in the machine direction, and a height of 0.70 to 12.0 mm can be measured in the thickness direction of the fabric, or generally 5 will not have a height that is slightly thicker than the fabric itself. The loops 54 and the like in Figs. 3A and 3B are preferably installed at the time of manufacturing the fabric, because their installation requires that CD yarns 50 and the like be woven through the loops. In particular, when the modified endless weaving is performed, the loops can be loaded on the loom from a storage tank. The tank is located near the edge of the fabric, and a loop is inserted when each pair of MD yarns is weaving. The edge thread for the MD yarn to be woven back will pass through the tank and through the interior of all loops. When each yarn is driven into the fabric, a loop is inserted. Another variation is that most edge threads are used, and MD yarns and the like are sequentially knitted, and when each other yarn is driven in, a loop is inserted. 15 When the fabric is plain woven, the fabric is mounted on a sewing table when a pin seam is to be formed. A storage tank will be installed along the entire edge of the fabric, containing properly spaced loops and having a "loop forming pin" passing through it. When each MD yarn is folded back to form a pin around the loop, one loop is inserted into the structure between the two MD loops. 20 The rings 74, 82, 84, etc. in Figs. 4A and 4B can be installed in a manufacturing plant, a paper mill, or an industrial device in which the industrial fabric is to be used. The loops can be stored in a storage tank or installed or distributed on a belt or cardboard strip to facilitate their installation. The loop forming pins will be removed, and the loops will be snapped into place, which can be spread over the entire width, or a section of the width 17 200402495 degrees, or placed one by one in pairs of yarns between. A connecting pin would then be inserted over the entire width through the rings to connect them to the fabric body. This process is similar to inserting a spiral to create a spiral seam. The loops are contained in a storage tank, which can be a tube with an open side 5 and spacers, etc., to keep the loops properly spaced for use in a particular fabric. Alternatively, the loops can be attached to an adhesive tape with a portion of their perimeter until they fit into the fabric. If the industrial fabric is a crimped fabric with plied / twisted MD yarns, the loops are installed before heat setting and needling, which will prevent the 10th-class sewing loops from being relatively perpendicular to the fabric plane. This phenomenon is commonly known as the second helix effector. The amendments of the above examples will be easily known to professionals, but still not exceed the scope of the attached patent application. For example, if the fabric is provided with a fleece, the substrate, whether plain woven or modified endless weave, will have loops on each edge of the 15 fabric. After needling, the seam is opened and the wool pad is cut in a conventional manner, and the fabric is installed on the machine to be used. The loops will be installed in the edges of the fabric using a tank or tape as described above. This can be used for pressing fabrics, needle-punched dry fabrics, and corrugated belts. The crimped fabric 20 may be a plain weaver, or it may be woven by a modified endless weaving method, or may be made of a strip of spiral material, and stitched as previously described.
